Overdrive--Love it!

I've been downloading recorded books for a couple of years now. I haven't explored much of the Video offerings, but with the books--there are a couple of areas that could be improved.

I wish there were more search options. It's mostly a browsing catalog. I've found that using the browser's back button after adding a title to my cart is the only way to return to my search results without starting over. I've started at the Sno-Isle catalog and access an Overdrive title from there when I have a particular title or author in mind. I'm hoping for some helpful hints from other users for more searching ideas!

Patrons complain that they can't return a title early. I find myself maxed out with the 10 titles often, so I know how they feel.
But all in all, I couldn't live without the service!
